A web browser is a software application that allows you to access, retrieve, and view web pages and other information on the internet. The browser serves as the main tool for navigating the internet and provides the means to interact with and make use of the vast wealth of information that it offers.

The web browser works by sending a request to a web server, which then sends back the requested information in the form of a web page. This process is known as “request-response”. When you type in a URL or click on a hyperlink, the browser sends a request to the server to retrieve the page you have requested. The server responds by sending the page back to the browser, which then displays the page on your screen.

One of the key features of a web browser is its ability to render HTML, which is the markup language used to create web pages. The browser takes the HTML code and turns it into the visually appealing and interactive pages that we are used to seeing on the internet.

There are many different web browsers available, each with their own unique features and strengths. Here are five of the most popular browsers and some of their distinguishing features:
